Angle-Based (ABOD[1]}) , Copula-Based (COPOD[2]}, Stochastic Selection(SOS[3]}) are known as probabilistic techniques used for OCC. Combining several methods of OCC are known as ensemble techniques those include Isolation Forest (IF[4]}), Locally Selective Combination of Parallel Outlier Ensembles(LSCP [5]}), Feature Bagging(FB [6]}), Extreme Boosting Based (XGBOD [7]}), etc.
